外贸网站建设公司平台廊坊百度提升优化

   门户网站用户端需要分板块展示，板块内容由管理端配置，包括板块名称，访问路径，路由组件，展示顺序，是否展示。如下图所示：

用户访问门户网站时，展示菜单跳转通过板块配置，动态生成路由。

1.后端接口获取路由

 @GetMapping(value = "/router")public Result<?> getRouterList() {LambdaQueryWrapper<Block> query = new LambdaQueryWrapper<>();query.eq(Block::getIsShow, true).orderByAsc(Block::getSort);List<Block> blockList = blockService.list(query);List<Map<String, Object>> routeMapList = new ArrayList<>();blockList.forEach(block -> {Map<String, Object> map = new HashMap<>();map.put("path", block.getPath());map.put("component", block.getComponent());map.put("name", block.getComponent());routeMapList.add(map);});return Result.OK(routeMapList);}

2.路由配置文件  router/index.ts

import {createRouter, createWebHashHistory} from 'vue-router'const router = createRouter({history: createWebHashHistory(), // hash模式：createWebHashHistory，history模式：createWebHistoryroutes: [{path: '/404',component: () => import('@/views/404.vue'),hidden: true},]
})export default router

3.路由守卫  router/guard/index.ts

import {Router} from 'vue-router'
import {getRouterList} from "@/api/block";
import mainStore from "../../store";let dynamicRouters = []export async function dynamicRouter(router: Router) {const {data: res} = await getRouterList()dynamicRouters = res.resultconst routeList = transformObjToRoute(dynamicRouters)routeList.forEach((route: any) => {//添加路由router.addRoute(route);});
}/*** views目录下找页面，设置component* @param routeList*/
function transformObjToRoute(routeList: any) {let dynamicViewsModules: any = import.meta.glob('../../views/**/*.{vue,tsx}');routeList.forEach((route: any) => {const component = route.component as string;if (component) {route.component = dynamicImport(dynamicViewsModules, component)}});return routeList;
}function dynamicImport(dynamicViewsModules: any, component: string) {const keys = Object.keys(dynamicViewsModules);const matchKeys = keys.filter((key) => {const k = key.replace('../../views', '');const startFlag = component.startsWith('/');const endFlag = component.endsWith('.vue') || component.endsWith('.tsx');const startIndex = startFlag ? 0 : 1;const lastIndex = endFlag ? k.length : k.lastIndexOf('.');return k.substring(startIndex, lastIndex) === component;});if (matchKeys?.length === 1) {const matchKey = matchKeys[0];return dynamicViewsModules[matchKey];} else if (matchKeys?.length > 1) {return;}
}/*** 页面未找到*/
export const PAGE_NOT_FOUND_ROUTE: any = {path: '/:path(.*)*',name: "NotFound",component: () => import('@/views/404.vue')
};/*** 动态路由权限控制* @param router*/
export function setupPermissionGuard(router: Router) {router.beforeEach(async (to, from, next) => {//判断是否已经添加过动态路由，添加过，直接放行if (mainStore.getters.getIsDynamicAddedRoute) {next();return;}//没有添加过，添加，添加后跳转页面await dynamicRouter(router)router.addRoute(PAGE_NOT_FOUND_ROUTE);mainStore.commit('setDynamicAddedRoute', {isDynamicAddedRoute: true})next({...to, replace: true})});
}

4.main.ts配置路由守卫

import App from './App.vue'
import router from '@/router'
import {setupPermissionGuard} from '@/router/guard'async function bootstrap() {// 创建应用实例const app = createApp(App);app.use(router) // 引用路由实例setupPermissionGuard(router);await router.isReady();// 挂载应用app.mount('#app', true);
}bootstrap()
